The history is short. I bought it for 15€. The device couldn't read any disc. I opened and the lens was not in the laser pickup. It's a typical fault in these series Pioneer laser pickups. I searched the lens but it was not inside the laser pickup. I thought to remove a lens from some Pioneer lasers I have, but these lasers pickups cost 100 or 200€ in the market. It don't worth. Then, I thought to use a lens from a chinese scrapped Sony KSS-240 or similar... I put the lens, it fitted perfectly, a drop of glue... and it works! It works perfectly. I adjusted a bit the "radial and tangential tilt adjustment", focus offset to O volts and perfect.
P.S: In the Pioneer PD-4700 service manual is where the grating adjustment is best descripted. If you want to know how to adjust the grating adjustment, there is the best description I ever found about it.
So, if you have a Pioneer laser pickup without lens because it had lost, get a chinese KSS and use its lens for to repair it.
